Abstract: High Resolution Image Download MS PowerPoint Slide Platinum Chini clusters with a general formula [Pt 3 (CO) 6 ] n 2– are formed by stacked Pt 3 units. They have fascinating electronic and optical properties that can be tuned with n . In the current manuscript, the electronic, photochemical, and charge transport properties of the platinum Chini clusters are studied with the density functional theory (PBE and CAM-B3LYP/6-31G(d,p)+LANL2DZ) as a function of their nuclearity number n . Our theoretical predictions are supported by experimental proof of concept, in which synthesized Chini clusters are deposited as cocatalysts on TiO 2 for photocatalytic hydrogen generation. We demonstrate that smaller clusters ( n = 4) are more effective than larger ones ( n = 7–8), and that composites having lower Pt content perform better.
